We'll admit to losing whole afternoons while perusing various Tumblrs (Suri's Burn Book, we're looking at you), but they're not all fluff. Calumet 412 , a Tumblr of "forgotten Chicago ephemera," is a collection of seriously awesome old pictures of the city. It's not all black and white or Kodakchrome photos—there are old business cards, postcards, and drawings. Subjects run the gamut from crime to transportation to sports, and date back to the 1860s. We'll stop raving about it now so you can go look at it.
